Compilers asked to optimize code for a more advanced CPU (for example the GNU Compiler with its -march=i686 option) generate code that uses CMOV. Linux systems intended to run on i686 are generally not compatible with these Vortex86 models because the GNU C Library, when built for i686, uses a CMOV instruction in its assembly language strcmp ...
Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.
The proprietary extension pack adds a USB 2.0 or USB 3.0 controller and, if VirtualBox acts as an RDP server, it can also use USB devices on the remote RDP client, as if they were connected to the host, although only if the client supports this VirtualBox-specific extension (Oracle provides clients for Solaris, Linux, and Sun Ray thin clients ...
The first implementation of the P6 core was the Pentium Pro CPU in 1995, the immediate successor to the original Pentium design (P5). P6 processors dynamically translate IA-32 instructions into sequences of buffered RISC-like micro-operations , then analyze and reorder the micro-operations to detect parallelizable operations that may be issued ...
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
The Pentium Pro is a sixth-generation x86 microprocessor developed and manufactured by Intel and introduced on November 1, 1995. [1]: D-2 It introduced the P6 microarchitecture (sometimes termed i686) and was originally intended to replace the original Pentium in a full range of applications.
They both provide CPU cache information in a series of sub-leaves selected by ECX - to get information about all the cache levels, it is necessary to invoke CPUID repeatedly, with EAX=4 or 8000'001Dh and ECX set to increasing values starting from 0 (0,1,2,...) until a sub-leaf not describing any caches (EAX[4:0]=0) is found. The sub-leaves that ...
Unicorn is a CPU emulation framework based on QEMU's "TCG" CPU emulator. Unlike QEMU, Unicorn focuses on the CPU only: no emulation of any peripherals is provided and raw binary code (outside of the context of an executable file or a system image) can be run directly. Unicorn is thread-safe and has multiple bindings and instrumentation interfaces.
